The 2009 Jeep Liberty remains true to its legendary 4x4 heritage by offering two Jeep Trail Rated four-wheel-drive systems – Command-Trac and Selec-Trac II.
Giving the 2009 Jeep Liberty that “only in a Jeep” open-air experience is the industry-exclusive Sky Slider full-open canvas roof. Chassis improvements for 2009 Jeep Liberty include stiffer rear axle shafts and retuned springs, shocks, anti-roll bars and steering gear valve. These enhancements provide a more precise, linear feel and improve steering and handling. Additional improvements to brake pedal feel are achieved through a retuned booster, low rollback calipers and a revised brake pedal ratio.
A 3.7-liter SOHC V-6 engine is standard on all Jeep Liberty Sport and Limited models sold in the United States. The 3.7-liter SOHC V-6 engine provides the 2009 Jeep Liberty with competitive peak power and torque while providing smooth, quiet operation and proven durability. It produces 210 horsepower (157 kW) @ 5,200 rpm and 235 lb.-ft. (319 N•m) of torque @ 4,000 rpm. Fuel economy is estimated at 16 mpg city and 22 mpg on the highway.
Whether it’s rock crawling in Moab, Utah, or making its way through a snow-covered highway, the 2009 Jeep Liberty’s four-wheel-drive systems meet customer needs. Selec-Trac II,® a full-time four-wheel-drive system and Command-Trac,® a part-time four-wheel-drive system are available.
The Selec-Trac II four-wheel-drive system is a full-time, active on-demand system that anticipates and prevents wheel slip before it occurs. It is ideal for a wide range of road settings, including dry pavement conditions not typically suited for conventional part-time four-wheel-drive systems. Command-Trac is a part-time four-wheel-drive system. Its front driveshaft is disengaged from the transfer case, and power is directed to the rear wheels.
